Preparation of poly(acrylamide-co-Acrylic acid) hydrogels in presence ofcellulose nanowhisker(CNW) : mechanical and morphological study

The applications of hydrogels are severely limited by their weak mechanical properties. Herein, wedevelop a physico-chemically cross-linked Poly (Acrylamide-co-Acrylic acid) hydrogel (Poly(AAmco-AAc)) , which are reinforced by cellulose nanowhiskers (CNWs). Mechanical (tensile test) andmorphological (SEM) studies show the effective role of the presence of nanoparticles (CNWs) andphysical secondary network (coordination between Fe۳+ and -COO- groups) in improving themorphological integrity and improving its mechanical properties.
